SPECIFICATION forming part of Letters PatentNo. 768,380, dated August 23, 1904:.

I Application filed April 6, 1904. Serial 110,201,801. (No model.)

To. all whom, it may concern:

Be it known that I, FRANQOIS Lnoounr, a.- citizen of the Republic of France, residing in Sevres, Seine-et-Oise, France, have invented, certain new and useful Improvements in Stop: pering Bottles, Jars, or Like Vessels, of which the following is a specification.

This invention relates to certain improvements in stoppering-bottles, jars, and like vessels, whereby a very hermetic stoppering of the said vessels is obtained, combined with ease of opening.

'According to my invention I employ a cap.- sule made in one piece, the bottle being adapted to be opened by tearing away a strip from the turned-over edge of the said capsule, the said strip being removed by the edges of an internal strip or band placed between the capsule and the flange on the neck of the bottlewhen a pull is exerted on the said tearing strip or band. The turned-over edge of the capsule has no weakened part formed in the metal,

- which is sometimes the case, but which is inconvenient in practice, as the metal gives way along the weakened lines should the bottle be subjected to a high temperature, such as boiling-point. The edges of the internal tearingband are sufliciently sharp to cleanly detach th? metal around the circumference of the capsu e.

My capsule is formed with a concavity at the top. This concavity allows the metalto bulge when the bottle or the like is subjected to a high temperature, such as boiling-point, and subsequently retake its normal form under the effect of cold.

In order to enable the invention to be understood, I will describe the same by reference to the accompanying drawings, in which Figure 1 is an elevation, partly in section, of my stoppering device. Fig. 2 is a horizontal section, and Fig. 3 is a sectional view, of a bottle-neck, showing my invention applied thereto.

The capsule is in one piece and is formed by stamping from a tin-plate blank. The upper part has a concavity a, and apart 6 projects circularly above the capsule. Externally and a little lower is a plain circle 0, which joins the top d of the turned-over edge of the capsule. These two parts 0 d of. the capsule serve to .hold-therubber washer in position and to make a-tight joint at the top of the bot-.

tie-neck. When the capsule is pressed down to effect the stoppering, the washer ev is compressed, thusinsuring a perfectly-tight joint.

The continuation of the turned-over edge 'ofthe capsule is of a diameter a little largerat the party to form a grooveonrecessto receive within itthe tearing strip or bandh,

which is applied in advance, so that at the same operation both the capsule and the internal band, which serves to tear away the an extra thickness.

The external tongue 0 is grasped with an ordinary key, on which is rolled the band for tearingthe metal from the capsule along the two edges of the said tearing-band. The stop The end is of the of the capsule is thus detached and the bottle is unstoppered.

Having now partlcularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I clai1n is 1. A metal capsule stamped from a single blank for bottles, jars, and like vessels, provided at the top with a downwardly-curved concavity a to allow of the capsule bulging outward when the bottle, jar or the like is subjected to a high temperature such as the boiling-point.

- 2. A metal capsule stamped from a single blank for bottles, jars, and like vessels, provided at the top with a downwardly-curved concavity a to allow of the capsule bulging outward when the bottle, jar or the like is subjected to a high temperature such as the boiling-point, and provided with portions 0 and (Z bent toward each other to form arecess to receive a washer for making a tight joint.

3. The combination with a metal capsule stamped from a single blank for bottles, jars and like vessels, provided at the top with a downwardly-curved concavity a to allow of the capsule bulging outward when the bottle, jar or the like is subjected to a high temperature such as the boiling-point, of a strip or band carried by said capsule, the end of the said strip passing through the capsule to the outsideand adapted to be grasped and to cause a strip to be torn from the capsule the lower end of which is turned under the flange on the bottle-neck.

4. The combination with a metal capsule adapted to be fastened upon the mouth of a vessel to close the same, of a band carried thereby and adapted to be pulled to tear the capsule so as to release it from the vessel.

5. The combination with a metal capsule adapted to be fastened upon the mouth of a vessel to close the same, of a band adapted to be pulled to tear the capsule so as to release it from the vessel, said band being fastened to said capsule so that it is applied to the ressel therewith.

6. The combination with a metal capsule adapted to be fastened upon the mouth of a vessel to close the same and having a groove 0 below the top of the capsule, ol a strip carried within said groove and adapted to he pulled to tear the capsule so as to release it from the vessel.

7. The combination with a metal capsule adapted to be fastened upon the mouth 01 a vessel to close the same, of a strip carried within said capsule and adapted to he pulled to tear the capsule so as to release it from the vessel, said strip having the ends bent around a portion of the capsule so as to fasten it to the capsule.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
